An immunoassay is a method used by many different fields of science to determine the presence of an analyte in a sample. The method is based on the interaction between the antibodies and the analyte, and the results can be reported in concentrations, positive/negative or greater than/less than thresholds.
Immunoassays are used in academic, pre-clinical and clinical research, clinical diagnosis and in supporting technologies in many different fields of science such as pharmaceuticals, veterinary, forensic, military and food sciences.
Commercially available assays are designed and optimized for specific analytes, sample types, sample volumes and ranges. The protocol contained with the product should be strictly followed, without deviation, to obtain the most accurate and reproducible results.
